The object of this research is to establish a new method for evaluating the inner pore structure of porous materials, such as porous anodized aluminum electrodes, porous glasses, silica catalyst supports, and inorganic metal oxide catalysts.The process of this technique includes that (1) vacuum heating of both a monomer of replicating polymer and porous samples in a vacuum cell, (2) mixing in vacuum, (3) introducing of air into the vacuum cell, (4) polymerizing of the monomer, (5) crushing of the polymer-porous sample complex, (6) dissolution of of thD porous sample, (7) observation of the replica of the pore structure by scanning electron microscopy (SEM).The characteristic of this research is that the successful selection of a phenol novolak epoxy resin (Araldite), which is resistant to acid corrosion and vacuum heating, ane this replication method can be adapted to the evaluation of pore structure of variuos kinds of porous materials. Following porous materials have been observed by this method.1. Anodized porous aluminum electrodes2. Glass filter3. Silica catalyst support4. Hydroxy-apatite

本研究的目的是建立一种评价多孔材料（如多孔阳极氧化铝电极、多孔玻璃、二氧化硅催化剂载体和无机金属氧化物催化剂）内部孔结构的新方法，该方法包括（1）将复制聚合物单体和多孔样品在真空室中真空加热，（2）在真空中混合，（3）将空气引入真空室，（4）单体聚合，（5）聚合物-多孔样品复合物的破碎，（6）多孔样品的溶解，（7）利用扫描电子显微镜（SEM）观察孔结构的复型。本研究的特点是成功地选用了酚醛环氧树脂（Araldite）具有耐酸性腐蚀和耐真空加热的特点，该方法适用于各种多孔材料的孔结构评价。通过该方法观察到以下多孔材料.阳极氧化多孔铝电极2.玻璃过滤器3.二氧化硅催化剂载体4.羟基磷灰石
